A gas is cooled as it flows through parallel tubes 5 extending between headers 6, 7 within a casing 1, the tubes being supported in hollow plates 2, 3, each comprising a plurality of hollow tubular section members 4 joined together in pressure tight manner. The members 4 may be arranged in a stepped formation as shown or in a generally flat formation (Fig. 4), and may be annular and arranged concentrically as shown, or straight and arranged side by side (Fig. 4). The hollow members 4 are provided with perforations 10 allowing the cooling medium to enter the members, and also to allow any generated steam to pass from the members into the casing 1. The steam is withdrawn through riser tubes 11 provided in the upper end plate 3. The riser tubes 11 may pass through the wall of the gas outlet header (7A, Fig. 4). Alternatively and as shown, the heat exchange tubes 5 may extend beyond the plate 3 and be anchored at their ends to a plane end plate 13, and the riser tubes extend through the space between the plates 3 and 13 to a steam outlet manifold 12.

Abstract: 1448528 Matrix displays RCA CORPORATION 19 Dec 1974 [2 Jan 1974] 54888/74 Heading G5C [Also in Divisions H3-H5] A liquid crystal device with rectifying electrical characteristics comprises liquid crystal material between two electrodes and a layer of semiconductor material disposed between, and in physical and electrical contact with, one of the electrodes and the liquid crystal material. Particularly described in a coincidence addressed X-Y matrix display device, in which the rectifying characteristics reduce cross-talk and in which the semiconductor and/or liquid crystal layers may be continuous or physically separated into elements corresponding to the electrode intersections. The electrodes may comprise a plurality of figure of eight arrays for use in a watch. The device is believed to be similar to a barrier diode, with the semiconductor layer being in ohmic contact with the electrode and in rectifying contact with the liquid crystal material. The semiconductor material is preferably transparent, with a bulk resistivity of less than 10<SP>6</SP> ohm-cm., and insensitive to light (band-gap greater than 2À5 eV.), for example, zinc sulphide or sputtered zinc oxide. The forward and reverse resistances of the diode should have a ratio of at least 1 : 100 or more and should fall on either side of the resistance of the liquid crystal material. If the liquid crystal material contains dopants, the redox potentials thereof should be related to the termi levels of the semiconductor material, e.g. an organic bromide for a termi level of 4-5 eV. By selection of suitable semi-conductor material, the device may be addressable electrically and optically.

Patent GB-562279-A (GB)
Abstract: 562,279. Galvanometers. GALL, D.C. Dec. 23, 1942, No. 18246. [Class 37] A moving coil instrument movement has a diametric rigid contact arm connected to one end of the coil, or an additional coil, and a pair of limit stops formed as electric contacts, in circuit with a source of current, such contact of the arm with either limit stop causing a current to pass through the coil, or additional coil, which tends to move the movement away from that stop. The moving coil 1 of a mirror galvanometer carries a stop arm 2 which is connected to one end of the coil 1 or of a separate coil. The arm 2 is arranged so that its ends can make contact with pins 3 which serve as limit stops. These pins are adjustable and can be locked in adjusted position. Both pins are connected to one end of an iron-cored coil 4, the opposite end of which is connected to the opposite end of the coil 1 or the special coil, so that current passes through this coil only when one end of the arm 2 is in contact with one of the stop pins 3. Sufficient voltage is induced in the coil 4 by stray-fields from neighbouring transformers &c. to produce a small alternating current in the coil which shakes the coil clear of its stop. The coil 4 may be replaced by another source of weak alternating current, or direct current may be employed. Specification 27298/07, [Class 37], is referred to.

Title: A roller mill
IPC: B02C15/00
Filed: 1978-07-03
Abstract: In a rolling mill having a rotary bowl supported by horizontal and vertical bearings independent of an output gear wheel, drive is transmitted from a step-down transmission by an arrangement including self- centering couplings clutching a vertical drive shaft to the bowl and the horizontal output gear wheel. The drive shaft, by canting slightly, is able to transmit drive without lateral thrusts from the bowl to the gear wheel. As a result, wear of the gear wheel teeth produced by small misalignments of the axis of the bowl and gear wheel during operation of the mill is avoided and the life of the mill is prolonged. Provision is made for vertical removal of the shaft and the splined diameter at the lower end is less than that at the upper end to facilitate this. Involute teeth are used for the splines. <IMAGE>

Abstract: A peak-limiting apparatus and method particularly useful in systems employing high frequency pre- emphasis to compensate for steep high frequency rolloff in a receiver, or the like. The apparatus and method is useful in standard AM broadcasting to maximize loudness without noticeable distortion.
